They usually fail at the power receptacle jack. These are great sandals and are similar if not identical to their All-Terrain sandals from the 80s. Superficially I like the green color and was looking to avoid austere colors like black or white. Fits perfectly on the buds case but it also comes off easy which is both a good and bad thing. Decent arch support and made with great quality. Easy to install with hardware supplied. I wasn?t expecting it to be this good for the price. I had 2 in my last house installed on inside of cabinets. My son(7 year old) loves it. The microphone seems a bit hit and miss when using Google assistant but that could be connection related but is good during calls.
